Question

不确定我的标题是否正确，这是我的第一篇文章，请原谅我，如果在其他地方得到解答，但我确实尝试研究它并试图找到特定于我的问题的答案。

我是Python新手，我正在构建我的第一个程序，一切正常，除了代码部分要求用户知道他们的名字长度。

我正在尝试为＆＃34;是＆＃34;添加多个答案。而对于＆＃34; no＆＃34;因此，如果用户输入的内容类似于＆＃34;是的＆＃34;或＆＃34; nope＆＃34;它仍然会接受答案。我为可能的答案建立了列表。然而，它只是跳过我的if语句，我的elif声明，并且直接进入我的其他声明。我也试过不使用列表，但＆＃34;和＆＃34;还有＆＃34;或＆＃34;没有运气。

# prints the length of name if user desires, if not it goes onto ask age

print('Would you like to know the length of your name?')
answer = input()
affirmative = ['yes', 'Yes', 'yeah', 'Yeah', 'yup', 'Yup', 'y', 'Y', 'yea',          
'Yea']
negative = ['No', 'no', 'Nope', 'nope', 'N', 'n', 'Nah', 'nah']
if answer == affirmative:
print('The length of your name is ' + str(int(len(myName))))
elif answer == negative:
    print('Ok! Thats fine! I didn\'t want to tell you anyway!')
else:
    print('Ok then.....next question')

我使用的是最新版本的Python。提前谢谢你，如果在其他地方得到了回答，那就再说一遍。

Answer 1

以下是一些可以帮助您的建议。

# prints the length of name if user desires, if not it goes onto ask age

answer = input('Would you like to know the length of your name?') 
# Rather than printing, input can take the string to print (helps with figuring out what the input is used for)
affirmative = ['yes', 'Yes', 'yeah', 'Yeah', 'yup', 'Yup', 'y', 'Y', 'yea',          
'Yea']
negative = ['No', 'no', 'Nope', 'nope', 'N', 'n', 'Nah', 'nah']
if answer in affirmative:
    print('The length of your name is ' + str(int(len(myName))))
elif answer in negative:
    print('Ok! Thats fine! I didn\'t want to tell you anyway!')
else:
    print('Ok then.....next question')

通过使用in关键字，您可以检查您的字符串是否在列表中。

Answer 2

   # prints the length of name if user desires, if not it goes onto ask age
           # prints the length of name if user desires, if not it goes onto 
   ask age

    answer = input('Would you like to know the length of your name?') 
   # Rather than printing, input can take the string to print (helps with figuring 
    out what the input is used for)
    affirmative = ['yes', 'Yes', 'yeah', 'Yeah', 'yup', 'Yup', 'y', 'Y', 'yea',          
    'Yea']
    negative = ['No', 'no', 'Nope', 'nope', 'N', 'n', 'Nah', 'nah']
   if answer in affirmative:
        print('The length of your name is ' + str(int(len(myName))))
    elif answer in negative:
      print('Ok! Thats fine! I didn\'t want to tell you anyway!')
    else:
       print('Ok then.....next question')

使用列表在if，elif，else语句中定义多个答案
